[Bug target/111165] [13 regression] builtin strchr miscompiles on Debian/x32 with dietlibc

--- Comment #20 from Thorsten Glaser <tg at mirbsd dot org> ---
I would like some assistance in debugging this further. I had been able to work
around this by…

-static int varsub(Expand *, const char *, const char *, unsigned int *, int
*);
+static int varsub(Expand *, const char *, const char *, unsigned int *, int *)
+#if defined(__GNUC__) && (__GNUC__ >= 13)
+    __attribute__((__noinline__))
+#endif
+    ;

… but now, on GCC 14, again with dietlibc on x32, it happens again, so the
underlying problem is still present.
